AUGUST J. KLONECK, OF NEW YORK, N. Y.

SPEEDOMETER.

Application filed October 25, 1915.

To all whom it may concern:

Be it known that I, AUousT J. KLoNnoK, a citlzen of Germany, and aresldent of New York, in the county and State of New York,

have invented certain new and useful Improvements in Speedometers, ofwhich the following is a specification.

This invention relates to improvements in speedometer-s and has for itsobject to provide a speedometer with a fan for the inclication ofvarying speeds.

Another object of the invention is to provide a speedometer with arotating propeller and means whereby an air current, caused by saidrotating propeller is utilized to indicate the speed thereof.

Still another object of the invention is to provide the speedometer witha funnel or jacket, whereby an air current, produced by said propellermay circulate and continuously be used.

l/Vith these and other objects in view, I have invented the deviceillustrated in the accompanying drawings in which:

The figure is a sectional elevation view of my improved speedometer.

In the drawing, 1 indicates a casing, housing a rotatable mountedpropeller or fan 2. The latter is rigidly secured to the driving shaft3, which may in any suitable manner be connected to the device, whosespeed is to be measured. Another propeller or fan l is arranged abovethe first named propeller 2, without any mechanical connection betweenthem however. Said fan 4, would rotate proportional to an air currentproduced by the propeller 2. The rotation of said fan 4, however isretarded by a convenient spring 5, permitting a rotation of the fan 1 offew degrees only. A scale may be engraved on a convenient part of fan 4,which permits a direct reading of the propeller speed or the drivingdevice. Through a funnel 7 formed by a jacket of the speedometer the aircurrent produced by propeller 2 may circulate, thus preventing dust orother impurities to enter the speed indicator.

The speedometer may further be provided with a revolution counter of anyform, the construction of which is not essential for the presentinvention. I have shown a counter S, which is operated by a treadedportion 9, on the circumference of propeller 2.

Having fully described my invention, that Specification of LettersPatent.

Patented Nov. 21, 1916.

Serial No. 57,743.

which I claim as new and desire to secure by.

Letters Patent is:

1. In a speedometer, an outer casing, an inner casing positioned at aside thereof and a mechanically driven fan and an air driven fan locatedin said central casing.

In a speedometer, an outer casing, an inner casing positioned at a sidethereof'and a mechanically driven fan and an air driven fan located insaid central casing, said two casings forming a passage for air currentstherebetween.

3. In a speedometer, an outer casing, an inner casing positioned at aside thereof and a mechanically driven fan and an air driven fan locatedin said central casing, said two casings forming a passage for aircurrents therebetween, said outer casing being entirely closed.

4:. In a speedometer, an outer casing, an inner casing positioned at aside thereof and a mechanically driven fan and an air driven fan locatedin said central casing, said two casings forming a passage for aircurrents therebetween, said outer casing being entirely closed and arevolution counter on said outer casing and means within the casing foroperating the same.

5. In a speedometer, an outer casing, an inner casing positioned at aside thereof and a mechanically driven fan and an air driven fan locatedin said central casing, said two casings forming a passage for aircurrents therebetween, said outer casing being entirely closed and arevolution counter on said outer casing and means within the casing foroperating the same, said means consisting of a gear on said mechanicallydriven fan.

6. In a speedometer, an outer casing, an inner casing positioned at aside thereof and a mechanically driven fan and an air driven fan locatedin said central casing, said two casings forming a passage for aircurrents therebetween, said outer casing being entirely closed, said airdriven fan having an indicator scale on the periphery thereof.

7. In a speedometer, a fan having a speed indicator thereon, saidindicator consisting of a scale on the periphery of said fan, meanswhereby said fan may be operated by an air current, said fan beingspring controlled, said means consisting of a mechanically driven fan, acasing in which said fans are 8. A speedometer consisting of an airdriven spring controlled rotary fan and a mechanically driven fan, saidfirst fan carry- 111g a speed indicator on the periphery thereof, saidlast fan being provided with means for operating a revolution counter.
